False teachers/doctrine can be identified. The only remaining question is whether or not we care to identify them and contend for the faith. It is easier to go along with the status quo than to challenge it. And standing up for truth requires that we ourselves know the truth. However, to fail to contend for the faith is to be derelict in our service to Christ.

We must contend for our faith, by fighting for holiness, standing against false teaching and demonstrating, by the obedient lives we live, the truth of the Gospel: that it is possible for a man to live for God, it is possible to be holy.
